Aly Raisman spent months urging the U.S. Olympic Committee and USA Gymnastics to get serious about taking a long, hard look into how Larry Nassar‘s abusive conduct was allowed to run unchecked for so long.

Frustrated by what she considers a lack of progress, the six-time Olympic medalist hopes she can get some answers in court.

Raisman filed a lawsuit against both organizations, claiming they “knew or should have known” about abusive patterns Nassar, a disgraced former national team doctor now in prison for sexually abusing young athletes.

Raisman filed the lawsuit in California on Wednesday.

The filing alleges negligence by the USOC and USA Gymnastics for failing to make sure appropriate protocols were followed in regards to monitoring Nassar.

Nassar, who is named as a co-defendant in the lawsuit, is serving decades in prison for molesting some of the sport’s top athletes and others as well as child pornography crimes.

The 23-year-old Raisman, captain for both 2012 and 2016 U.S. Olympic champion gymnastics teams, says she was abused by Nassar in multiple locations beginning in 2010, including at the U.S. national team training facility at the Karolyi Ranch training center in Texas and the London Games.

Raisman said she initially felt she was receiving medically necessary treatment by Nassar before realizing it was abuse. She battled shame, guilt and depression in the aftermath, Raisman said.

Nassar spent nearly three decades at USA Gymnastics before being fired in 2015 after complaints about his behavior. He continued to work at Michigan State University through fall 2016 before being hit with federal charges.

Raisman said the USOC and USA Gymnastics allowed Nassar to continue abusing athletes by not telling the university about the conduct that led them to fire him.

USA Gymnastics and the USOC broke their stated mandates to protect children in their programs by not revealing Nassar’s past misconduct to athletes and their parents or guardians, the lawsuit said.

Raisman joined a list of more than 100 civil actions filed against Nassar and USA Gymnastics. Olympic teammate McKayla Maroney named the USOC as a co-defendant in a lawsuit she filed last December.

USA Gymnastics and the USOC did not immediately respond to a request for comment from The Associated Press.

Raisman, who has become a vocal critic of both organizations after initially revealing the abuse in her autobiography released last fall, did not plan to go to court but says she felt compelled to press forward because she believes USA Gymnastics and the USOC are not making a sincere effort to “properly address the problem.”

“I refuse to wait any longer for these organizations to do the right thing,” Raisman said in a statement. “It is my hope that the legal process will hold them accountable and enable the change that is so desperately needed.”

The USOC is conducting an independent review of when former CEO Scott Blackmun and others learned the details about abuse cases at USA Gymnastics and whether they responded appropriately.

Blackmun stepped down earlier this week to deal with prostate cancer, though Raisman, several high-profile gymnasts and two U.S. Senators called for his ouster for weeks.

USA Gymnastics underwent a massive overhaul in the last year.

Former president Steve Penny, named as a co-defendant in Raisman’s lawsuit, resigned last March. Longtime chairman of the board Paul Parilla, another co-defendant in the suit, and the rest of the board stepped down in January under heavy pressure from the USOC. USA Gymnastics also ended its relationship with the Karolyi Ranch in January and is currently searching for a new training center.

“It has become painfully clear that these organizations have no intention of properly addressing this problem,” Raisman said. “After all this time, they remain unwilling to conduct a full investigation, and without a solid understanding of how this happened, it is delusional to think sufficient changes can be implemented.”

Raisman’s lawsuit claims both organizations focused on medals instead of the well-being of the athletes, a model that allowed Nassar’s behavior to go unchecked for years.

The lawsuit says the USOC “had a culture and atmosphere that conceals known and suspected sexual abusers, which transcends all policies and procedures that are set-in place.” Raisman believes the USOC ignored its own mandates “to protect its reputation and blind itself to known abusers within the ranks of the NGBs (National Governing Bodies) for which it is responsible.”

NUR-SULTAN, Kazakhstan — Matt Lindland sees progress taking place within the United States Greco-Roman program.

He sees accountability and ownership. He sees a desire to compete with the global Greco powers and a willingness to pay the price to get there.

“There’s definitely been progress,” Lindland said. “We’ve got great guys. It’s about them. They want to be here. They want to do what it’s going to take to get to that next level, and you can see it. They’re frustrated when things don’t go their way, and they’re going to figure out how to fix those things. Yeah, we’re making the right progress. We’ve got the right guys, we’ve got the right attitude.”

But Lindland also sees hesitation at times, too. He sees too much analyzing and not enough reactionary aggression.

“I think our guys are second-guessing themselves, they’re questioning and they’re thinking,” he said. “They’re thinking about what’s going to happen instead of being in the moment and just being present and letting things fly. Really great athletes out there on America’s team and they’re super capable. When they start thinking and questioning what’s going to happen and wondering what the referee is going to call, they’ve just got to go out there and do what they’re all capable of doing.”

Both dynamics — the signs progress and the work-in-progress symbols — were on display Saturday on the opening day of the World Championships.

Max Nowry, Ryan Mango and Raymond Bunker notched opening-round wins Saturday. For perspective, only three Americans posted Greco victories at the World Championships in 2018.

On the flip side, though, each of the three ran into roadblocks when they couldn’t hold leads in their second bout, and Mango and Bunker got eliminated later in the day.

Nowry and John Stefanowicz, however, got pulled into the repechage and have a chance to wrestle Sunday for medals. Nowry got an extra opportunity when Kazakhstan’s Khorlan Zhakansha stunned 2018 World champ and No. 1 seed Eldaniz Azizli of Azerbaijan, 11-5, in the 55-kilogram semifinals.

Stefanowicz dropped a 7-0 decision in the Round of 16 at 82 kilograms against Georgia’s Lasha Gobadze. But the Georgian posted two more victories to set Stefanowicz up with another chance at a medal.

Sky Brown, an 11-year-old who appears en route to becoming the youngest female Summer Olympian in 50 years, took third at the world skateboarding championships in Sao Paulo on Saturday. The sport debuts at the Olympics in Tokyo.

Brown posted her highest score of her four finals runs in the last round, 58.13 points, of the park event. It was not enough to overtake Japanese Misugu Okamoto and Sakura Yosozumi. The new world champion Okamoto is 13 years old. Yosozumi is 17.

Brown has been raised in Japan by a Japanese mother and a British father. The 2018 Dancing with the Stars: Juniors winner appeared in a Nike “Dream Crazier” ad with Simone Biles, Serena Williams and Chloe Kim in February.

She has not clinched an Olympic spot yet but is well on her way as the qualifying season continues.

She turns 12 years old just before the Tokyo Olympics begin and would be the youngest Olympian since Romanian rowing coxswain Carlos Front at the 1992 Barcelona Games.

She would be the youngest female Olympian since Chinese ice dancer Liu Luyang in 1988 and the youngest female Summer Olympian since Puerto Rican swimmer Liana Vicens in 1968, according to the OlyMADMen.

The Tokyo Games feature four skateboarding events — men’s and women’s street and park.
